ADVERTISING DEVICE.

j To all 'whom t may concern novelactuating meansfor the panel carrier;

and'fourth, to provide details of structure whereby a simple, positively operated, and compact structure is obtained. v

I obtainvthe above mentioned objects together with other objects and corresponding accomplishments by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of a complete apparatus; Fig. 2 is alperspective on an en- -larged scale of details of the actuating mechanism, the foundation plate being `Vbroken away to better show theA mechanism; `Fig. 3 is a perspective view of Va fragment of the panel carrier, a panel arm and a fragment of panel being shown; Fig. 4 is a vertical section .through the device; Fig. 5 is an eleva.- tion of the drive shaftand panel carriers thereon, parts thereof being in section; Fig.

K `6 is a perspective view of a panel carrying disk; Fig. 7 is a perspective view of a locking disk; and Fig. 8 is an elevation of a panel frame which may be used instead of the arms shown in preceding views.

While the device is especially useful for advertising purposes, it may be employed to impart information, such, as for illustration, indicating streets on car routes or stations at which cars or trains may stop.

Referring more particularly to the drawing, a housing or casing isf-indicated by 9.

The front thereof may be open or covered by a transparent medium, such as glass, so that the panels within the easing in position for display lare visible. Suitablv journalled in Y the box and extending the lengt-h thereof is a shaft 10 and fixed to the shaft are panel carrying disks 11. The 'disks are provided with apertures 12 preferably arranged in a circle and spaced from each other. These Specification of Letters Patent.

apertures are designed to receive the ends of the panel carrying arms later described.

Cooperating with each carrying diskis a locking guard comprising two disks 13 and 13. Each locking disk has a notch 14. The locking disks are held in selected angular positions with respect to one another by a compression spring 15 mounted on the shaft intermediate the locking guards. In the construct-ion shown herein bushings 16 are slidably mounted upon the shaft between the ends of the spring and the locking disks to cheapen the construction; Spring 15 presses the members of a pair of locking disks against each other, their frictional resistance holding them in adjusted position.

Fixed upon the shaft 10 at one end thereof is a ratchet wheel 17. A base plate 18 serves as a foundation for carrying one j ournal of shaft 10 and the advancing mechanism. Mounted upon the base plate 18 is a black 19. A bracket plate 2O is secured to the block, and pivotally mounted between the plates is a lever 21 carrying at one end a pawl 22 for moving the ratchet Wheel. A retractile spring 23 is secured to the lever 21 find to the base plate. Lever`21 forms the armature for an electromagnet V24 disposed so as to move the lever against the action of spring 23. The winding of electromagnet- 24 is in circuit with a source of electrical energy and an interrupter 25. This interrupter may be mechanically, thermally, 0r otherwise operated so as to make and break the circuit at determined intervals. Upon energizat-ion of the electromagnet, lever 21 is moved Vcausing pawll 22 to advance the ratchet wheel a step.

Mountedin the bloclc19 is an abutment screw 26 for limiting the retracticle movement of lever 21. By adjustment of the screw 26, the magnitude of the steps advanced Jy the ratchet wheel will be regulated. ".Divotally mounted in the other end of block 19 is a locking pawl 27 for preventing the ratchet wheel from being moved in the reverse direction.

Arms 28 are mounted upon the carrying disks, andA panels secured to the arms. Referrii g to the arm shown in Fig. 3, it consists )f a wire bent at Aright angles to itself .t one end to form a pintle 29 and haviig an eye 30 at the other end. The arms are mounted upon the carrying disks by inserting the pintles in the apertures 12. As :fach arm is inserted in position the the same direction.

' pintles.

notches 14: di a pair of lockingdisks are caused to register with each other, and the' aperture receiving the pintle. After the construction just described is. such that sin-l gle arms may conveniently be removed oi changed.: VVhereit is intendedthat aset ofarmsvbe maintained and changed onlyas a set, arsingle locking disk without a notch ln this case the locking.v

may be employed. di'skimust be held away from the Acarrying disk while changing the arms.

Theupanels are mountedV upon thearms by passing fasteners 32 through the -eyes 30E and corresponding 'apertures in thev panel.

The number of carryingdisks and arms may bevari'ed. Herein l have 'shown two. The panels may be cut away-as shown in Fig.'

1 to accommo'date'theni to Ythe disks. In: F ig. 8 a panel' framey is shown consisting of av single piece'of wire or the like with arms having pintles 33 and 34 facingin The panel is bordered by the frame. Only one guard-is necessary, as by locking the pintle 34 to the carrying disks in the manner of pintles 29 at the right of Fig. 5, the frames are se-A cured" against displacement.

Mounted in the casing 9at the top thereof is a gate 35 against which the panels may rest while being displayed in their upper position.' An opaque plate 36 may screen eithery the lower or upper panel in displayed position as desired, so that one only is visible. This is useful for certain purposes;

Thefdeviceloperates inthe following manner:

Theyinterrupter 25 intermittently energi'z'es the ele'cti'omagnet 24 causing it to ad- Vance tlieratchet wheel step by step. This causes an intermittent rotationl of the shaftl lOand the disks 11, causing the arms 28 to be revolved, the latter pivoting upon their A panel attached to two corresponding arms will hang. downwardly in a vertical position displaying the matter imprinted on one side of thepanel- As the panel moves backward, the succeeding panel drolisfroinv its upper vertical position in front ofthe lower panel displaying one side of the succeeding panel to view. As the arms are carried inwardly they rest against the pintle of the following arm andare supported thereby eventually reaching a vertical' position displaying the other side of the panel. After passing the vertical`position, they drop downwardly turning about their pivot'pointson'the carrying disks. If it is desired to hold the panels in their upper position, the gate 85 is used. Thus, the other sides of each panel will be progressively displayed In* this manner, each sideflofthe1 panelis alternatlydisplayed, one side in the upper position and the other side in the lower position. eration-of the shaft 10, thepanelsarefdi'splayed for an intervalof time in their sta tionary position.

The panelsinay 3T mounted upon the casing.V If it is desired to screen' oneV side of 'the panel, tlier opaque screen 36 may be disposed above orV below the shaft i() tocutoff-the vision of either the panels in'their upperv or lower positions.Y This is advantageous,--wlierethe' device is used for indicatingst-reets onacar route.'l Correspondingsides of the panels mayv have the street-names*arranged in jone-v order, while the opposite sides mayl have the names arranged in the reverse,l order,

Thus, whentraveling in one direction,l the opaque screen is arranged so that thesides Due tol the intermittent opbe illuminatedy byv lights 1 of the panels havingthe street-s infoneorder -j of progression are visible. Upon return of the car over the rou-te, the screen tismovedl to display the other side of the panelsfwith thev seriesv of streets in the reverse order. The screen is alsouseful whenit isy desired to use transparent panels, and illuminate them. Such panels can only be exhibited. in either their upper or lower position. The

length of time that a panel is displayed may l be varied bypusingless carrying .arms and less panels. For illustration, -if four panelsare used instead of twelve, the time` that each panel would be displayed would'be three ltimes greater. The use ofi locking disks' makes it possible to vary the number of panels and interchange thepanels. The set Y screwfQG- also makes it possible tofvary the timeof exposure by varying'theamountfof motion of the pawl and-therefore'of]thef ratchet wheel at each vmovement of the` leven The gatevvis not essential to the-oper-a--v tion of the mechanism,-but is -useful tohold the panels at lany desired angle-or position. before they Vswing downwardly to makerooml for the nextpanel. Y It is `obvious thatfany mechanical variations of the structure may.

be resorted to without departing rfromf the spirit' of the invention` What Iclai-m is: f ,Y
